After my little tumble at Cadwell a few days ago I was told a slipper clutch would have saved me, anyone have one of these fitted to their bike?
Was also told the tuono has a Back torque limiter? If mine does it doesn't work, anyone know anything about this or has he made it up? Or and it's a 2004 tuono.
Cheers

It does have something on it, bigralphie explained it a while ago in another thread. You should not blip the throttle when changing down, as this effects it. I've had to change my riding style to accomodate this.

not sure if the gen 1 has the vacum system like the gen 2 but it will have a back torque limiter and as grin says the blipping of the throttle when changing down does affect the system. have a read of the attached mate, the thread below may be helpfull if you ignore the banter:

Yes the Gen1 Tuono has the same vacuum slipper as the Gen2.Its pretty basic tbh and the effect will never be the same as the ball and ramp type.
The idea is that the vacuum lifts the clutch plates slightly to create a 'slipper' effect.That goes out of the window if you blip the throttle on downward changes as all the air disapears.
The ball and ramp type is not effected by blipping but at around £600-£800 for a clutch hub,....they aint cheap.I think you have to be a serious track day freak or racer to get the full benefit.Sigma,MPL and STM all make slipper clutches for the RSV/Tuono.

Had slipper clutch on my RSVR which worked well, but to be honest clutch control can do the same job,feather the clutch on the bite point if the back is feeling naughty, worth practising to get the hang of. The torque of a twin can take some adjusting to with the amount of engine braking,compared to in line fours.Cadwell has some steep fast down hills leading into corners requiring some measured gear selection and brake control .

I clumsily changed down a while ago (dont think I blipped the throttle) & the back wheel locked up going into a corner.

I agree, blipping the throttle will render the "slipper clutch" useless - by design.

But blipping the throttle when changing down (if done corrrectly) will bring the engine speed upto the wheel.

I think ??? Unless someone out there can correct me.

There's a one way valve (white plastic) under the tank, that may have gone. Blow through it to find out, it should only pass in one direction.

When I'm downshifting rapidly through a few gears, I always blip it, but I hold the revs on and wind the throttle back at a measured pace. You can then apply a little engine braking as required by gently rolling off.

Since I posted I have played a bit ,the slipper on the T works after a fashion but you can catch it out if you shut off hard and drop a couple cogs in a oner
I rode a ZX12R with 180bhp at back wheel (and no slipper) for 7 years so my throttle control is pretty good and as said by Tifa if you hold a few revs on your change down it will smooth the whole plot.
On the Ninja I used blip the throttle with my finger and thumb ,on the T I am just resting the throttle on the pad of my thumb.

BUT a sigma slipper clutch is a cracking bit off kit my mate has one on his 999 he swears by em

Slipper clutches are also lighter to opperate, 'cos the engine's torque tends to engage them (so the springs don't have to) My Hayabusa clutch is lighter that my Tuono's!
